WINDOW SASH CONSTRUCTION Filed May' 20, 1950 Patented June 7, 1932 UNITED STATES CHARLES E. CONNER AND HARRY C. AINSXVORTH, 0F TORR-ANC-E, CALIFORNIA WINDOW sasrr CONSTRUCTION Application filed May 20,

This inventionrelates to an improved window sash construction adapted to be applied to windows having a single sash, and also applicable to windows of the double sash type. I

An object of the invention is to provide a window sash construction which will'make it possible to put the glass in place in the sash in a safer and more convenient manner, thus not only avoiding needless danger of breaking the glass but also saving the time ordinarily consumed by workmen in attending to this part of the Work.

Another object of the invention is to pro vide a window that can be more safely and conveniently washed, the device being so con structed that it is not necessary to remove the screens when washing the windows. This feature is particularly valuable in washing windows two or more stories above the ground floor.

Still another object is to provide a window sash construction which is better adapted to provide indirect ventilation, and which may be more conveniently and dependably adjusted to regulate the amount of fresh air admitted to the room.

Still further objects are to provide a window that can be repainted with greater convenience and safety, and one which can be manufactured and installed in a convenient and inexpensive manner without making it diiiicult for workmen to adapt themselves to the improved features embodied by the invention.

Other objects and advantages may hereinafter appear.

Referring to the accompanying drawing which illustrates what is at present deemed to be a preferred embodiment of the invention,

Fig. 1 is a vertical section of a window having a pair of composite sash constructed according to the principles of the invention.

Fig. 2 is a face view of a window provided with two sashes each of which is constructed as shown in Fig. 1, the lower portion of the view being broken away to contract the size thereof.

Fig. 3 is a reproduction on an enlarged 1930. Serial, No. 452,949,

scale of the central portion of Fig. 1, showing a catch element which requires a larger scale for illustration than the scale of Fig. 1. Fig. 4 is a plan View of a-portion of both the upper and lower sash, illustrating the position of the catch element shown in Fig.3. r a Fig. 5 is a face view of a toothed plate which forms a part of the means for varying the ventilation through the'window, a portion of the plate being broken awayto contract the view. I w Fig. '6 is a cross section online 66 of Fig.7 is an'end'v-iew of'Fig. 5. Referring in detail to the drawing, the sash construction coin-prises for each of the compound or composite sashes, an outer sash element 7 and an innersash element 8. The inner sash element 8 is fitted within the outer 7 sash element 7 with a convenient working fit, and these two sash elements are secured together, preferably by a pair of hinges 10, to pivotally fasten the lower edge of the inner sash -8 to the adjoining edge of the outer sash 7 I 7 Our improved window sash construction is shown mountedin a well known type of window frame having thesill 11, side pieces 12, and top piece 13. It is adaptedto be constructed at the factory of proper dimensions to fit standard window frames to be supplied with the invention.

The downward swing of each inner sash 8 is limited by means of a pair of links 14,each of said links having one of its ends pivotally connected with the inner sash at 17, there being a rec'ess18 cut into the edge of the sash adjoining the pivotal connection 17 in order to-provide room for the linkto swing relatively to the sash as the inner sash is adjusted toward and from the closed position. The upp-er'end of each link 14 is provided with a laterally deflected portion 20' thus forming a latch finger. With said latch finger cooperates the teeth 21 of a latchplate 22. Said latch teeth 21, as viewed in Fig; 5, aredirected upwardly and projected toward thecenter of a slot 25 whichextends lengthq Wise of plate 22 at substantially its midwidth. Each of said teeth 21 is directed upwardly to give it the shape of a ratchet tooth and is provided at its upper end with a shoulder 26 upon which the finger of the link 14 rests to sustain the inner sash in the adjusted more or less open position. The width of the slot through the plate 22 is sufficiently great to permit the finger 20 to pass upwardly across the points of the teeth 21 when it is desired to move said finger 20 from a lower tooth to a higher tooth of the series of teeth 21. Each link 14, as well shown in Fig. 7, may consist of a. single metal rod bent as shown, having an eyeleted lower end portion to receive the pivot screw 17 and having its upper end deflected to form the offset portion 20 which cooperates with the seats or notches 26.

In the drawing the slotted plate 22 is shown as having end flanges 22a and side flanges 22b to-conceal the metal or wood along the sides of the recess into which said plate is fitted.

One advantage secured by providing the links 14: in combination with the toothed plates 22 is that this arrangement enables the window washer to adjust each of the inner sash to a substantially horizontal position, as indicated in dotted lines in Fig. 1, in order to wash the outer sidesof the glasssafely and conveniently.

Owing to the fact that theinner sash 8- is, at its lower edge, pivoted to the outer sash 7, and the links 14, deflected at their upper ends, cooperate with the teeth 26 of the plates 22, said links do not become released from said teetheven if the inner sash be slightly lifted from a horizontal or inclined open position.

In Figs. 3 and 4 is illustrated a locking device or sash catch 30 which is adapted to swing to a concealed position when unlocked, thus permitting the lower sash to be moved until its upper edge comes in direct contact with the upper window frame element 13 to permit what is shown as the upper sash in Fig. 1 to be brought down to a sufficiently low level with relation to the lower end of the other sash so that the inner sash'elem'ent 8 may be swung inwardly, that is to say to the right as seen in Fig. 1, without its upper edge being obstructed by the lower edge of the other sash, that is the sash which is shown as the lower sash in Fig. 1. Said locking device 30 comprises a hook portion '35, an operating stem 36 and a pivot pin 37, said locking device 30 being housed Within a recess 40 provided therefor in the sash to which it is pivotally secured.

We claim:

1-, In a window construction, an outer sash, an inner sash hinged at their lower edges to said outer sash, a link having one end pivotally secured to said outer sash, said link having a deflected portion at its free end,

there being a series of seats provided along an inner edge of said outer sash to cooperate with said deflected portion of said link to maintain the inner sash open to the extent desired.

2. In a window construction, an outer sash, an inner sash hinged at their lower edges to said outer sash, a link having one end pivotally secured to said outer sash, said link having a deflected portion at its free end, and an elongated metal plate secured to an inner edge of said outer sash, said plate having a slot extending lengthwise thereof and a series of ratchet teeth out into an edge of said slot, said ratchet teeth being engageable by the deflected portion of said link. I

In testimony whereof we hereunto afiix our signatures.
